Connect one external service to your existing product without leaving brittle glue code behind. I’ll implement one documented API integration—from authentication and data mapping to webhooks, retries, tests, and handoff—inside your current backend. Good fits include an AI provider, payment service, CRM, email platform, or data API. This scope covers one provider and one primary workflow. What’s included: • Integration plan, field mapping, and success criteria • Authenticated API client for one agreed provider • One primary request, sync, or webhook workflow • Validation, retries, error handling, and useful logging • Automated tests, configuration notes, and a handoff walkthrough Send me the API docs and your current setup, and I’ll tell you the cleanest way to connect it.
